What this calculator does
This tool converts time between the standard 12-hour clock (using AM and PM) and 24-hour ‘military’ time, the format used by the armed forces, hospitals, and international schedules to avoid AM/PM ambiguity.
How the calculation works
Converting to military time keeps the hour the same in the morning (12 AM becomes 00) and adds 12 to PM hours (so 1 PM becomes 13:00). Converting from military time subtracts 12 from hours after noon and labels the result AM or PM based on whether the original hour was before or after 12:00.
This tool is intended for general scheduling and educational reference.
